A blow-by gas recirculation structure for an engine includes a gas-liquid separating member (4 and 14, 24, 34), a cylinder head (3), a support member (9, 29) and a mounting bolt (10, 110, 210, 310, 410). The gas-liquid separating member (4 and 14, 24, 34) includes a gas-liquid separating passage (100) to separate oil from the blow-by gas. The cylinder head (3) includes a communication passage (3c) communicating with the air intake system. The support member (9, 29) is configured and arranged to rotatably support a camshaft (7) in the cylinder head (3). The mounting bolt (10, 110, 210, 310, 410) securely fastens the support member (9, 29) to the cylinder head (3) with the mounting bolt (10, 110, 210, 310, 410) threadedly engaging within the communication passage (3c) of the cylinder head (3). The mounting bolt (10, 110, 210, 310, 410) has an axial through hole (10a, 110a, 210a, 310a, 410a) axially extending there-through and communicating with the gas-liquid separating passage (100) so that the blow-by gas that has passed through the gas-liquid separating passage (100) is recirculated from the axial through hole (10a, 110a, 210a, 310a, 410a) of the mounting bolt (10, 110, 210, 310, 410), through the communication passage (3c), and into the air intake system. |
